Beilstein Handbook Reference) BRN 1719943 2-Butenoic acid, (Ej- (E)-2-Butenoic acid trans-2-Butenoic acid (E)-Crotonic acid Crotonic acid, (E)- trans-Crotonic acid EINECS 203-533-9 NSC 8751. Synthesis of resins, polymers, plasticizers, drugs. Prisms or needles mp = 72° bp = 184.7° d = 0.9604 very soluble in H2O (54.6 g/l), EtOH, soluble in Et20, Me2CO, ligroin LD50 (rat orl) n 1.0 g/kg.

Crotonic Add n (trans-2-butenoic acid, trans- P methacrylic acid) CH3-CH=CHCOOH. A white crystalline solid prepared by the oxidation of crotonaldehyde. It forms copolymers with vinyl acetate, used as hot-melt adhesives. Esters of crotonic acid are used as plasticizers for acrylic and cellulosic plastics. [Pg.183]

Poly(vinyl alcohol) has the structure 10.67. Poly(vinyl acetate) is the fully esterified derivative of polyfvinyl alcohol), in which the -OH groups are replaced by -OCOCH3 groups. As indicated in Table 10.5, commercial polyvinyl sizes are effectively copolymers of polyfvinyl acetate) and polyfvinyl alcohol) that vary in the degree of saponification of the ester groups. These products may comprise 100% of either polymer, or combinations of the two monomers in any proportions. Crotonic acid (2-butenoic acid), widely used in the preparation of resins, may also be a component. This compound exhibits cis-trans isomerism (Scheme 10.17). The solid trans form is produced readily by catalysed rearrangement of the liquid cis isomer. [Pg.98]

When the RelSi terminology (29) was introduced (28), its use was suggested also for describing the faces of double bonds. This was to be accomplished by citing the descriptors of their trigonal atoms when seen from the same side. Although this extension seems an obvious choice, it is subject to a possible misinterpretation. If one characterizes a face of the olefinic bond of 2-butenoic acid as Re-Re, one can deduce that the compound in question must be the Z and not the E isomer. It might be inferred from this that the cis-trans isomerism of these acids can be factored into two elements of prostereoisomerism. This... [Pg.223]

The crude 3-(4-biphenylyl)-2-butenoic acid is dissolved in 200 ml of dry tetrahydrofuran and 4 ml (0.055 mole) of thionyl chloride is added. The solution is refluxed under a nitrogen atmosphere for 3 hours and the solvent and excess thionyl chloride then distilled off. The resulting residue is flash distilled in a microdistillation apparatus at 145-153°C/0.075 mm to yield the 3-(4-biphenylyl)-2-butenoic acid chloride, substantially in trans form. [Pg.3477]

The reactive intermediates A and C could be so short-lived that they cyclize extremely fast. They certainly could cyclize so fast that the trans-configuration of the 2-methyl-2-butenoic acid moiety by and large is carried over into the cycloadduct. Intermediates A and C would therefore hardly have enough time to isomerize to conformers B and D, respectively, by way of a rotation about the C—C single bond between the two C atoms that used to be connected by a configurationally stable C=C double bond in the starting ester. However, it seems unbelievable that not even as little as 0.003% of either of the potential intermediates would have... [Pg.679]

In the reaction of (Z)-2-bromo-2-butenoic acid the cyclic product (495) has the trans configuration. Since the cyclization reaction proceeds with inversion, the adduct formation is suprafacial. This is further confirmed by the reaction between 2-bromocyclohex-2-enone and mercaptopyridines where it has been shown that the dihydrothiazole and the cyclohexane rings are c/s-fused. [Pg.705]
